† NOTICE: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation of the device at those or any other conditions above those
indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability.
This device is sensitive to ESD damage and must be
handled appropriately. Failure to properly handle and
protect the device in an application may cause partial
to complete failure of the device.
